4 Claims. (c1. 294-58) Thisfinvention relates. to an auxiliary and detachable handle for shovels, forks and otherhandle-bearing tools.

,In the use of shovels and other handle bearing tools now on the market, the user has to grasp a hand gripwith one hand and then grasp the handle with the other hand at some place between the hand grip and the blade. Thus to scoop up a load of dirt or other material, the user must bend well over to carry outthe operations of lifting and disposing of the load to one side. This is not only unduly tiring, but involves the necessary effort to raise the users body to an erect discharging position. While it has heretofore been proposed to equip handlebearing tools, such as shovels and the like, with an auxiliary handle to lessen the effort in shoveling, these have not fully met the requirements of effective control of the tool and the load,

.in that s ome, are too short to permit substantially erect to allow complete positive control of the blade and its load inthe" erect position. Said positive control as afforded by the present invention thereby permits a pushing force ontheblade, in additionto a pulling force, a direct rotational force and combinations thereof. Said control is exerted in such a manner as to allow the free universal action necessary to throw the load sideways, forward, backward, over-the-head, and combinations thereof,

It is an object of this invention to provide an improved auxiliary adjustable handle device for shovels, forks, and other handle bearing tools, having clamping members connected thereto, whereby the device may be adjustably mounted in desired positions on a handle of a shovel or like toolor which may, if desired, be permanently secured to such handles.

It is another object of the present invention to provide an improved auxiliary adjustable handle device for handle bearing :tools having clamping members connected thereto whereby the device may be adjustably mounted on tool handles of varying sizes.

It is further an object of this invention to provide an improved auxiliary handle device for handle bearing tools whereby said auxiliary handle can be locked in place on the tool handle when said auxiliary handle is not in use.

A still further object of this invention is to provide an improved auxiliary handle device for shovels, forks, and other handle bearing tools that'permit the user to load, lift or discharge at or from a level below his foot level while remaining in an upright position.

A still further object of the present invention is to providean improved auxiliary handle device for handle bearing tools that permit direct universal control of the tool blade.

,Other objects and many of the attendant advantages of this invention will'be readily appreciated as the same 2,772,910 Patented Dec. 4, 195 6 ice a preferred embodiment of the present invention attached thereto. l I Fig. 2 represents a side elevation of a spade with a preferred embodiment of the present invention attached thereto. i

.. Fig. 5 is an enlarged elevated view of another embodia ment of the clamp of the present invention shown. mounted on the regular handle of a spade with the latter being shownfin cross section. p H

, Fig; 6 is an enlarged front elevation ofthe handle of the present invention shown as removably secured to the illustrateslthe degree of lateral movability of said auxiliary handle. a f l .Fig. 2 illustrates the relationship of the auxiliary handle and the spade handle, 12, of coventional spade,

; 11, when said auxiliary handle is secured to said spade handleby U-grip, 15. The U-shaped handle portion 15 hasftransverse portions adapted to extend on opposite;

' sides of 'the spadehandle 12. The .olfset portion 15 is r inclinedsufficiently to permit notched grip 16 to grasp verse movability'of said auxiliary'handle.

. The..:V-.clamp,.member or, yoke,; 17,.is so shaped a'sfto 1 form substantially a wedge-shaped space in which the spade handle 12 may be seated. The strap 18 completes the triangular form to provide a three-point contact with the spade handle, 12, thereby permitting the clamp to be used on handles of varying sizes. The lower end of auxiliary handle is bent in a substantially circular shape and hooked to the central connecting portion of the V- clamp 17. The connecting portion, by virtue of the triangular configuration of the clamp, has clearance with the spade handle 12 conveniently to permit the auxiliary handle to be attached in this manner. Nuts, 19, screw on to threaded portions of V-clamp, 17, to hold strap, 18, againstspade handle, 12. The strap, 18, as shown in Fig. 4, has elongated holes, 21, to facilitate adaptability of the clamp to varied size handles. However, it is under stood that said holes may be made circular or rectangular.

The clamp 17 can be affixed to the spade handle 12 without requiring any structural alteration of the spade 11. However, if it is desired to fasten the auxiliary handle more rigidly and more permanently to the spade handle,

12, an eye bolt, 20, may be utilizedby passingthe shank of said eye bolt through a hole, 22, drilled through spade handle, 12... The lower portion of auxiliary handle is becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawing in which like reference numerals designate like parts throughout the figures thereof 7 and wherein:

Fig. 1 represents a perspective of a spade shown with bent in a susbtantially circular shape and hooked into the eye of eye bolt, 20, which is contained by nut, 19.

Fig.- 6, an enlarged view .of the U-shapedhandle por-v H tion 15, clearly illustrates same. Said handle" portion 15 is formed in a substantially U-shape so as to permit the arms thereof to grasp the 'spade handle, 12; A circular 7 provides the spring tension permitting it to securely grasp the/spade handle, 12, when the former is not in use.

It can be readily seen from Fig. 1 that if a user were to grasp the spade handle, 12, at its upper portion, with one hand,'and the grip 16, withthe other, he would be able to scoop up a load while remaining in an upright position thereby eliminating the necessity of stooping. The auxiliary handle would also permit a user to reach down below his own foot level while the user was in a substantially erect position. 7

Rotation of the auxiliary handle about its own 1ongitu'dinal "axis, by means of handle portion 15, would cause rotation of the spade handle 12, and blade 13, due to the rotation of V-c'lainp,.17, and eye bolt 20, asshown in Fig. 3 and'Eig. 5 respectively. ,Alsoa pushingfpi'ce can be exerted on the spade through the auxiliary'handl'e. The V-c'lanip, 17, and eye bolt, 20,-in conjunction with auxiliary handle .permitsubs'tantially universal'movement of auxiliary handle and also afford direct control of'the spade, 11, by the auxiliary handle.

It should be understood, of course, that the foregoing disclosure relates to only a preferredembodiment of theinvention and that numerous modifications or alterations may be made thereinwithout departing from the spirit and the scope of the invention set forth in the appended claims. a a
